<p>
<div>
<pre>llvm/lib/Support/NativeFormatting.cpp:244]: (style) Variable 'Len' is modified
but its new value is never used.
Source code is
unsigned Len;
Len = format(Spec.c_str(), N).snprint(Buf, sizeof(Buf));
if (Style == FloatStyle::Percent)
++Len;
S << Buf;
if (Style == FloatStyle::Percent)
S << '%';
}
I am not sure if local variable 'Len' needs to be used in some
way, or can be safely deleted.</pre>
